Farm Aid has occurred every year since it’s start in 1985, making it the longest-running concert for a cause in pop music history. The benefit continues its support of family farmers, by accepting sponsorship only from companies that share its mission.

Since 1985, Farm Aid has provided a hotline for farmers. Originally, you would call 1-800-FARM-AID to provide immediate and effective support services to farm families in crisis.

Now Farm Aid has an online Farmer Resource Network which connects farmers to a network of organizations across the country that help them find the resources they need to reach new markets, change over into sustainable, more profitable farming practices, and survive natural disasters.

Farm Aid will be staged in Pennsylvania for the third time in its history. The leading economic influx in the state is agriculture.
